Feature: 1. Two‑in‑one multimeter with oscilloscope, it is more convenient to test parameters. 2. High‑accuracy test, accurate test and support multiple ranges. 3. Small size, easy to carry, and convenient to use when going out. 4. It is made of ABS material, strong and durable, and can be used for a long time. 5. When the multimeter is in use, it must be placed horizontally to avoid errors. Specification: Item Type: Multimeter Material: ABS Model: ET826 Battery: 1.5V 3 x AA Batteries (Not Included) Purpose: Used in electrical parameter testing Technical Parameters DC Voltage 400mV;4V/40V/400V/1000V AC Voltage 400mV;4V/40V/400V;750V DC Current 40mA/400mA;4A/10A AC Current 40mA/400mA;4A/10A Resistance 400Ω/4KΩ/40KΩ/400KΩ/4MΩ/40MΩ Capacitance 0.1nF~100μF;10000μF Frequency 5HZ~5MHZ Diode Open Circuit Voltage 1.5V .How to Use: (1) Before using the multimeter, you should perform "mechanical zero adjustment", that is, when there is no measured power, make the pointer of the multimeter point to the position of zero voltage or zero current. (2) In the process of using the multimeter, you cannot touch the metal part of the test pen with your hands. This can ensure the accuracy of the measurement on the one hand, and ensure your safety on the other hand. (3) When measuring a certain amount of electricity, it is not possible to transform gears while measuring, especially when measuring high voltage or large current, you should pay more attention. Otherwise, the multimeter will be destroyed. If you need to change gears, you should disconnect the meter pen first, and then measure after the gear shift. (4) When the multimeter is in use, it must be placed horizontally to avoid errors. At the same time, attention should be paid to avoid the influence of external magnetic fields on the multimeter. (5) After the multimeter is used, the transfer switch should be set to the maximum range of AC voltage. If you do not use it for a long time, you should also take out the battery inside the multimeter to prevent the battery from corroding other components in the meter.
